Trait Implementations

impl OptStrings for OptMappedStrings

fn message(&self) -> PropertiesResult<'_, &[u8], Self>

Returns an array with all messages, separated by b'\n'

fn message_offset( &self, node: NodeId, ) -> PropertiesResult<'_, Option<u64>, Self>

Returns the position of the first character of node’s message in Self::message, or None if it is out of bound, or Some(u64::MAX) if the node has no message

fn tag_name(&self) -> PropertiesResult<'_, &[u8], Self>

Returns an array with all messages, separated by b'\n'

fn tag_name_offset( &self, node: NodeId, ) -> PropertiesResult<'_, Option<u64>, Self>

Returns the position of the first character of node’s tag_name in Self::tag_name, or None if it is out of bound, or Some(u64::MAX) if the node has no tag_name

impl PropertiesBackend for OptMappedStrings

type DataFilesAvailability = OptionalDataFiles

fn map_if_available<T, U>( v: <Self::DataFilesAvailability as DataFilesAvailability>::Result<'_, T>, f: impl FnOnce(T) -> U, ) -> <Self::DataFilesAvailability as DataFilesAvailability>::Result<'_, U>

Applies the given function f to the value v if the value is available

fn zip_if_available<'err, T1, T2>( v1: <Self::DataFilesAvailability as DataFilesAvailability>::Result<'err, T1>, v2: <Self::DataFilesAvailability as DataFilesAvailability>::Result<'err, T2>, ) -> <Self::DataFilesAvailability as DataFilesAvailability>::Result<'err, (T1, T2)>

Returns (v1, v2) if both are available, or an error otherwise
